CLAMP.

Application filed January 20, 1923.

a device for clamping a piece of silk over a type form when printing imitation typewritten letters.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specically pointed out in the appended claim. Y

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which y Figure l is a plan view of a form showing the invention in use.

Figure 2 is a section on line 2 2 of Figure l.

Figure 3 is an enlarged View of one of the clamps.

Figure i is a horizontal section of one of the clamps.

Figure 5 is a detail view. Y

In these views l indicates a pair of clamps which are placed one at each end of the type form so that theyv will engage the ends of the silk strip 2 which is placed over the form in printing` imitation typewritten let- Serial No. 613,990.

ters. Each clamp consists of a box 3 having its top open and one side of which is provided with holes 4. A bar 5 is located in the box and this bar is provided with recesses 6 in one side for receiving the extensions 7 or the turning screws 8, these screws engaging the screw threaded holes 4. The heads y9 of 45. the screws are provided with sockets 10 .for receiving a pin wrench so that the screws'can be rotated. A strip of wood l1 is inserted in the box and this strip is to have the end vot' the silk strip placed around the saine, as'c shown at 12, and then the screws are tightened to clamp the wooden strip between one side of the box and the clamping bar 5.

From the foregoing description it will be seen that the ends of the silk strip are sel,55 curely held in the boxes. The silk can be attached after the form is locked up and can be changedor removed without removing or unlocking the form.

It is thought from the foregoing description that the advantages and novel features ofiny invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement et the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is Y A device of the class described comprising a box, a clamping bar located therein, screws engaging holes in the box and recesses in the bar for receiving the screws and a wooden strip engaged by the clamping bainl In testimony whereofv I aliix my signature.
